Effects of catch crops on the content of sulfur (S) and selenium (Se) in vegetables

Summary

Selenium is an essential nutrient for animals, humans and microorganisms. Se deficiency in humans has been linked
to a plethora of physiological disorders.
Increasing evidences point to an anticarcinogenic
potential of Se-compounds.
To address Se deficiency in the human diet, agronomists and plant breeders are pursuing complementary strategies to produce crops with greater Se concentrations.
Catch crops have been used successfully in agriculture, increasing nitrogen and sulfur content in the soil and avoiding nutrient leaching. In this experiment we study whether catch crops can have similar beneficial effects regarding Se.
